炼钢厂连铸机冷床液压系统管路漏油治理

液压传动是以液体作为工作介质进行能量传递和控制的一种传动方式,在冶金行业使用率偏高。液压油泄漏,不仅带来巨大的液压油消耗,而且对环境造成不同程度的污染,还存在着一定的安全隐患,影响液压设备的稳定运行,严重制约着公司的生产节奏。通过对液压站内、外的漏油原因进行分析,提出了相应的解决办法。通过减少系统振动、升级焊接方式,同时,选用性能优良的耐磨、耐高低温的密封件,液压油消耗大大减少,取得了显著的效果。

First neutron Bragg-edge imaging experimental results at CSNS

The neutron Bragg-edge imaging is expected to be a new non-destructive energy-resolved neutron imaging technique for quantitatively two-dimensional or three-dimensional visualizing crystallographic information in a bulk material,which could be benefited from pulsed neutron source.Here we build a Bragg-edge imaging system on the General Purpose Powder Diffractometer at the China Spallation Neutron Source.The residual strain mapping of a bent Q235 ferrite steel sample has been achieved with a spectral resolution of 0.15%by the time-of-flight neutron Bragg-edge imaging on this system.The results show its great potential applications in materials science and engineering.
